Subtle symptoms of lung cancer: Spot the signs of worsening lung health before it’s too late

Symptoms of lung cancer: If you’ve been losing weight without trying, it may signal your body is fighting something more serious

You might notice a cough that lasts longer than two weeks. At first, it seems harmless, almost routine, until it starts disturbing your sleep. You may also dismiss occasional breathlessness as a result of aging or inactivity, only to realise that everyday tasks like climbing stairs now leave you unusually out of breath. Coupled with unexplained weight loss or frequent chest infections, these subtle signs could indicate that your body is facing a deeper issue; lung cancer.

Experts suggest that over half of lung cancer cases are diagnosed only in their later stages, reducing survival rates. “Understand and recognising the early signs is vital for timely intervention and better outcomes,” says Dr Niti Raizada, Senior Director of Medical Oncology and Haemato-Oncology, Fortis Hospital, Bengaluru. “Lung cancer often disguises itself as common respiratory illnesses, which is why many patients are unaware until the disease has advanced. However, it’s essential to understand that early detection significantly improves survival rates,” she explains.

Dr Raizada explains how to spot the subtle indicators of lung cancer:

• Persistent cough: A cough that lasts more than three weeks, especially if it becomes progressively worse, could be an early sign of lung cancer. Whether it’s dry or produces phlegm, it warrants attention.

• Shortness of breath: Breathlessness, especially during routine activities, could indicate changes in lung function. Don’t dismiss it as aging or lack of fitness.

• Chest pain and discomfort: Recurrent pain in the chest, which may worsen with deep breathing, coughing, or laughing, is a sign to take seriously.

• Unexplained weight loss: If you’ve been losing weight without trying, it may signal your body is fighting something more serious.

• Blood-tinged sputum: Even small traces of blood in your cough should not be ignored. Seek medical evaluation immediately.

• Recurrent infections: Frequent bouts of bronchitis or pneumonia could be a sign that something is compromising your lungs.

• Hoarseness: A voice that sounds raspier than usual or changes in tone might indicate lung-related issues.
